Backround And Purpose: To investigate the incidence of complications related to propofol-based anesthesia and the factors associated with complications in children with radiotherapy.

Materials And Methods: Patients who underwent anesthesia for external beam radiotherapy between May 2013 and November 2017 were included in the study. We assessed the age/weight, sex, oncologic diagnosis, type of radiotherapy procedure, duration of anesthesia, applied agents, and complications related to anesthesia. Complications were evaluated between group I (only propofol group) and group II (propofol plus adjuvant drugs) as respiratory and cardiac.

Results: In 130 patients, sedation was given for 1376 radiotherapy procedures. Of these, 1274 (1140 radiation treatment sessions and 134 computed tomography simulations) in 126 patients were propofol-based and were included in the analysis. Although respiratory complications are the most common in both groups, there were no episodes of laryngospasm, broncospasm, and no use of advanced airway intervention. The rate of complication was significantly higher in only propofol anesthesia group than in patients treated with propofol plus adjuvant drugs. In the multivariate analysis, we found three factors that were significantly associated with the risk of complications: total dose of propofol (mg/kg) (p < 0.001), anesthesia with propofol alone (as compared to propofol plus adjunct agents) (p = 0.001), and diagnosis of neuroblastoma (as compared to other diagnosis) (p = 0.043).

Conclusion: Propofol-based anesthesia is preferred in order to minimize the rate of complications in radiotherapy anesthesia applications. The use of non-opioid adjuvants in combination with propofol to achieve a balanced anesthesia will also reduce the complications that may be encountered.

Simultaneous Presentation of Wilms' Tumor and Contralateral Ganglioneuroma in a Child: Case Report and Literature Review.

J Pediatr Hematol Oncol 2018 08;40(6):e400-e404

Pediatric Oncology, Istanbul Medical Faculty, Istanbul University, Fatih, Istanbul, Turkey.

We demonstrate a 4-year-old girl who presented with progressive, asymmetrical, firm abdominal distention and was diagnosed with synchronous Wilms' tumor and left para-aortic ganglioneuroma (GN). Although synchronous tumors in the pediatric population are commonly associated with malignancy-predisposing syndromes, the patient in question was found to be otherwise healthy and had no clinical evidence nor family history of a syndrome. This case is the second one in the literature diagnosed with synchronous presentation of Wilms' tumor and GN in a previously healthy child. In addition, a GN foci presumed to be a previous metastasis of a neurogenic tumor that subsequently matured to GN was depicted within a left para-aortic lymph node. We aimed to emphasize an extremely rare synchronous occurrence of these embryonal tumors, increase the awareness of physicians, and discuss the radiologic differential diagnosis and management.
